Abstract: Marking device (100) for implantation into a tissue (260), having a support structure (102) which is formed by at least one elastic metal wire, is compressible and is self-expanding and which, in an expanded state, encompasses an interior space (104), characterized in that the marking device (100) is designed to transform itself on its own from a compressed state into an expanded state, even against a tissue pressure prevailing at a tissue site to be marked, and the marking device (100) in the expanded state has a hollow, approximately spherical shape.

Abstract: The invention relates to a marker body (10) for marking breast tissue for radiotherapy. The marker body (10) has an at least partly tube-like body (12) which is made from a soft elastic material and carries multiple radio-opaque marker elements (18). The at least partly tube-like body (12) is designed so that it offers hardly any resistance to an external, deforming force, but returns to its original shape in the absence of external forces. The at least partly tube-like body (12) has two free longitudinal ends (14, 16) which can be detachably interconnected or are interconnected, resulting in a tubular ring.

Abstract: The invention relates to a marker element for marking body tissue. The marker element has an at least approximately rotation-symmetric geometry about a longitudinal axis, is formed by interlinked, elastic and preformed wire members and can assume a radially compressed and a radially expanded state. The wire members are interlinked at their respective ends, preferably in pairs.

Abstract: The invention relates to a marking element for marking body tissue. The marking element has a shape which is at least approximately rotationally symmetrical about a longitudinal axis, and the marking element consists of interconnected preshaped elastic metal braces and can assume a radially compressed state and a radially expanded state. In the expanded state, the marking element is constricted in a central longitudinal section and expands continuously from the central longitudinal section towards the two sides in the longitudinal direction. The marking element has two widened longitudinal sections, the maximum outer diameter of which is two times to twenty times larger than the outer diameter of the central longitudinal section in the expanded state of the marking element.

Abstract: A biopsy holding device for a biopsy cannula to perform transcutaneous biopsies, in particular of hard tissue and bone marrow tissue, uses a wire that can be inserted into the proximal end of a biopsy cannula and can be pushed in between the inner wall of the biopsy cannula and the tissue-removing biopsy cylinder.
